What are the steps and focus and the core of performance appraisal please

I think the core of performance appraisal is performance (performance to speak). First of all, there is a clear goal (the company's goals into personal goals). Determine the goal of five principles 1, write down 2, quantitative standards 3, public 4, as large as possible 5, can not achieve what. Steps are roughly: the goal as the core: attitude (mentality, whether the work is serious) - skills (flexibility, proficiency) - action (will be willing and methods into the results of the process).
